How to make button bar look like Penny Arcade's version?

Can anyone help me? I want to figure out how to put the buttons in a bar and how to move the preview and save draft buttons to bottom, both which I can't figure out.

Got the second part of your question covered: You need to create two new folders in your /themes/default folder. The first one is called "views" and inside of that you create one called "post". You should now have a path that looks like this: /themes/default/views/post/
Inside of the "post" folder you create a new file called "comment.php". Now take the contents of the following gist: https://gist.github.com/2419542 and put them inside your comment.php file and you're done.

As for the first part, simply create a file called custom.css and put it in the folder /themes/default/design. Then put the contents of this gist https://gist.github.com/2419725 inside your custom.css file and you've got yourself a button bar like the one on Penny Arcade

@Caio I'm completely self-tought, began when I was 15 and I'm 18 today. I'll be going to the IT University of Copenhagen to study software development and math some time next year, so I can gain some more theoretical knowledge on the subject.

kasperisager do you have another link to that gist.github link you provided to post directly into the custom.css file within /themes/default/design? It seems to have disappeared since April.
